2.6.9.3 PCIe GbE Ethernet

Two PCIe x1 lanes are connected to two Broadcom BCM5787M PCIe GbE controllers
shown in Figure 2-9 below.

Figure 2-9: Broadcom PCI GbE Controllers

The Broadcom BCM5787M is a 10/100/1000BASE-T Ethernet LAN controller. The
BCM5787M combines a triple-speed IEEE 802.3 compliant Media Access Controller
(MAC) with a triple-speed Ethernet transceiver, a PCIe bus interface, and an on-chip
buffer memory. Some of the BCM5787 controller features are listed below:
Integrated 10/100/1000BASE-T transceiver
Automatic MDI crossover function
PCIe v1.0a
10/100/1000BASE-T full/half-duplex MAC
